Other things, maybe even ask your dad. How old is the community, and how bad are the monthly condo fees? This can play into maintenance costs, one-time assessments for large projects if they are about to come due, etc.
Also, the board/group that governs (forgot the dang name), are there politics going on that suck? I've seen some unhappy people in a condo complex where I lived, because they couldn't stand someone on the committee. It influenced a couple decisions, though ti couldn't really be proven.
